Need to know what is the proper fuel pressure for the Bendix RSA5 fuel injection system on an IO-320.
I can't seem to locate a document to tell me what pressure it should run at throughout the rpm range.Aux. fuel boost pump is regulated at 29psi but when off engine runs with 12psi to 22psi fuel pressure depending on rpm. Having problem with fuel smell when pump is on. Not leaking at pump or regulator and could possibly be forward of firewall. Not Good. Thinking too much pressure. Should have a return path for the overflow which I can't find.Only use aux pump for T/O and Lndg.Any help appreciated.
